Answer:
In a triangle, sides opposite of congruent angles are congruent.
1) Find the value of x. Round to the nearest tenth.
Answer:
x ≈ 12.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{9}{x}[/tex] ( multiply both sides by x )
x × tan35° = 9 ( divide both sides by tan35° )
x = [tex]\frac{9}{tan35}[/tex] ≈ 12.9 ( to the nearest tenth )
the volume of a cube is 710 cm cubed work out the length of its side rounded to one decimal place
Answer:
8.9cm
Step-by-step explanation:
Volume of a cube = L × L × L = L³
710 = L³
L = ³√710
L= 8.9 cm
The length of each side of Cube is 8.9 cm.
What is Volume of Cube?The length is to be multiplied by itself three times to get the volume. The volume is measured in cubic units.
For example, cubic units.
Given:
Volume of a cube is 710 cm.
So, Volume of Cube = l³
710 = l³
l = ∛710
l = ∛ (71 x 10
l = 8.9 cm
Hence, the edge length is 8.9 cm.

Multiplying by 0.05 is the same as decreasing by _____%.
Answer:
95%
Step-by-step explanation:
When a value is multiplied by 0.05 ;
The equivalent percentage decrease on the value is :
(1 - 0.05) * 100%
0.95 * 100%
= 95%
Therefore, Multiplying a value by 0.05 is the same as decreasing by 95%
is 15m 36m 39m right triangle
Answer is below. Look at my explanation to understand my answer.
To see if these lengths can make a triangle, we can use the "triangle side theorem."
The formula is:
a + b > c
a + c > b
b + c > a
So, with that being said...
15 → A
36 → B
39 → C
So, we can use the triangle side theorem by adding A & B, A & C, and B & C.
If the side length is greater than C, B, or A, it can make a triangle. But if it isn't greater than C, B, or A, it cannot make a triangle.
So, let's add 15 and 36 to see if it can make a triangle.
15 + 36 = 51
If you read above, C is 39.
So, 51 > 39
15 + 36 > 39 ✓
Let's repeat this process again.
Instead of C, B is what we're now seeing if the sum is greater than it.
15 + 39 = 54
54 is greater than 36...
54 > 36
So it is true.
15 + 39 > 36 ✓
Now, A is what we're seeing if the sum is greater than it.
36 + 39 = 75
75 is greater than 15...
75 > 15
So it is true.
36 + 39 > 15 ✓
So yes, these lengths can make a triangle.

–6x − 8y = –14
y = –2
Answer:
x = 5
Step-by-step explanation:
If you input the y-value into the equation you get x = 5.
-6x-8(-2) = -14
-6x+16 = -14
-6x+16-16 = -14-16
-6x = -30
(-6x)/-6 = (-30)/-6
x = 5

what is the approximate radius of the bowl shown that is shaped as a hemisphere
Answer:
Approximate radius of the given hemisphere is 3 in.
Step-by-step explanation:
Formula to calculate the volume of a hemisphere is given by,
V = [tex]\frac{2}{3}\pi r^{3}[/tex]
Since, volume of the given hemisphere in the picture = 56.52 in²
By substituting the value of V in the formula,
56.52 = [tex]\frac{2}{3}\pi r^{3}[/tex]
Now solve the expression for the value of 'r',
r³ = [tex]\frac{3}{2\pi }(56.52)[/tex]
r³ = 26.99
r = ∛(26.99)
r = 3 in.
Therefore, approximate radius of the given hemisphere is 3 in.
Julie can pack 18 hampers in 5 hours, Kyle can pack 14 hampers in 4 hours. Julie and Kyle work together to pack a total of 40 hampers. If they continue to work at the same rate, how long will it take them to pack the 40 hampers? Give your answer in hours and minutes, to the nearest minute.
Answer:
It will take 1 hour and 25 minutes to pack the 40 hampers
Step-by-step explanation:
Julie can pack 18 hampers in 5 hours
Kyle can pack 14 hampers in 4 hours
Julie and Kyle work together to pack a total of 40 hampers
Work done by Julie in one hour = 18/5
Work done by Kyle = 14/4
Work done all together
14/4 * 4 + 18/5 *5 = 40 * 1/x
14+18/40 = 1/k
K = 40/32 = 1.25 hours

List all the elements of the sample space for the following experiment: You roll a die and toss a penny.
Its not B
Answer:
Answer A.
Step-by-step explanation:
There is a 1/2 chance of getting either heads or tails on a coin since there are only two sides. That means that half of the pairs should contain H and half should contain T.
There is a 1/6 chance of rolling every number on a die. So this needs to be represented with the numbers 1-6 on every pair.
So if we combine both of those, 1-6 being on every pair and H being on half and T being on the other half, we get
1, H
2, H
3, H
4, H
5, H
6, H
1, T
2, T
3, T
4, T
5, T
6, T
Which is answer A.

Find the volume of the composite solid.
Here's the solution,
the volume of the given figure is :
=》
[tex]volume \: \: of \: \: (pyramid \: + rectangular \: \: prism)[/tex]
volume of pyramid :
=》
[tex] \dfrac{l \times b \times h}{3} [/tex]
=》
[tex] \dfrac{4 \times 5 \times 6}{3} [/tex]
=》
[tex] \dfrac{120}{3} [/tex]
=》
[tex]40[/tex]
volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》
[tex]l \times b \times h[/tex]
=》
[tex]4 \times 5 \times 2[/tex]
=》
[tex]40[/tex]
volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³
The volume of the composite solid will be 80 cubic cm.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as
V = L x W x H
The volume of the Pyramid will be given as,
V = (1/3) × Base area × height
Then the volume of the geometry will be
V = L x W x H + (1/3) x Base area x height
V = 5 x 4 x 2 + (1/3) x 4 x 5 x 6
V = 40 + 40
V = 80 cubic cm
Thus, the volume of the composite solid will be 80 cubic cm.
